Eigenmode Analysis of Galaxy Redshift Surveys I. Theory and Methods
We describe a method for estimating the power spectrum of density fluctuations from galaxy redshift surveys that yields improvement in both accuracy and resolution over direct Fourier analysis. The key feature of this analysis is expansion of the observed density field in the unique set of statistically orthogonal spatial functions which obtains for a given survey’s geometry and selection funct...
متن کاملEigenmode Analysis of Galaxy Distributions in Redshift Space
Eigenmode analysis is one of the most promising methods of analyzing large data sets in ongoing and near-future galaxy surveys. In such analyses, a fast evaluation of the correlation matrix in arbitrary cosmological models is crucial. The observational effects, including peculiar velocity distortions in redshift space, light-cone effects, selection effects, and effects of the complex shape of t...
متن کاملHigh redshift galaxy surveys
A brief overview on the current status of the census of the early universe population is given. Observational surveys of high redshift galaxies provide direct opportunities to witness the cosmic dawn and to have better understanding of how and when infant galaxies evolve into mature ones. It is a much more astronomical approach in contrast to the physical approach of to study the spatial fluctu...
متن کاملLocal redshift surveys and galaxy evolution
We present observations of galaxy environmental dependencies using data from the 2dF Galaxy Redshift Survey. From a combined analysis of the luminosity function, Butcher-Oemler effect and trends in Hα line strengths we find support for a model where galaxy properties are mainly set by initial conditions at the time of their formation.
متن کاملMock 2dF and SDSS galaxy redshift surveys
We present a comprehensive set of mock 2dF and SDSS galaxy redshift surveys constructed from a set of large, high-resolution cosmological N -body simulations. The radial selection functions and geometrical limits of the catalogues mimic those of the genuine surveys. The catalogues span a wide range of cosmologies, including both open and flat universes. In all the models the galaxy distribution...
